Application filed December 18, 1329. Serial No. 414,955.

This invention relates to a box and method of making it; and more particularly to the method of making a box with a display opening and means placed thereover to seal it and to displa articles inclosed in said box.

One the main objects of this invention is to provide a novel method for speedily and economically producing a sealed box provided with a transparent portion or display portion for displaying articles inclosed and protected in said box. Another object is to provide a novel method for speedily and efficiently securing covering means on a box which contains articles, so that said articles are inclosed sealed in said box and are also visible through said covering means. Still another object is to provide a novel method for quickly and economically producing a box or container with a body portion which is sufficiently rigid to aid in protecting articles contained therein, and whereby transparent or semi-transparent means is readily secured over an open portion of said body, so as to seal the same and the articles therein, and at the same time display said articles through said means. A further object is to provide a box comprising a body including a portion having an insert opening and transparent or display means secured thereover, whereby articles in the box are visible for display, and at the same time to make the box sufliciently rigid to provide protection to the articles therein, the entire construction being arranged so that the box can be very economically produced in its complete and sealed condition.

These objects and other objects and advantages are attained with this invention, as will become apparent from the following description, taken in connection with the accompanying drawing, in which- Fig. 1 is a perspective view of a complete body portion of a box or carton adapted for use in carrying my invention into effect.

Fig. 2 is an inverted plan view of the means used for covering and sealing the open portion of the box body to display the articles, being provided with adhesive means on the projecting edge flaps. Fig. 3 is a perspective view showing an early step in my novel method, whereby the sheet-like covering means is first secured with its adhesive means onto the side walls of the body.

Fig. 4 is a perspective view showing a succeeding step in this method, whereby the lower portions of the corners of said covering means are secured to the ends of the body, so as to leave the intermediate and .major portion of each end or sealing flap of said means still free.

Fig. 5 is a perspective view showing such major sealing portion of each end firmly sealed onto the end of the box, and also overlapping the greater parts of the lower corner portions previously sealed onto said ends, thus completely closing and sealing the box.

Fig. 6 is a perspective view of a blank of material having its corner portions cut-away, providing flaps which are bendable upwards for readily forming the box body.

Fig. 7 is a perspective view showing one of the four walls partly bent or folded upwards and the others fully so, in forming the box body, and before the covering means is secured over said walls to close and complete the box.

The novel method provided with this invention, for speedily and economically producing a sealed display box, may be practiced either by hand or by the use of an auto matic'machine, and is independent of any I particular machine. The main feature herein is that by this method a box or carton or container is quickly and economically produced in its complete and sealed form, to efiiciently store and protect articles inclosed therein, and at the same time to retain said articles visible for display. 1

In the drawing I have illustrated a ma ner or method of carrying my present invention into effect; and, for the purpose of illustration, I have in Fig. 1- shown a finished box body 10 which comprises a bottom wall 11 and upstanding walls arising therefrom to form opposite side walls 12 and end walls 13, and providing an upper opening 14: therebetween for the insertion and display of arti cles 15 in the box.

For the purpose of illustration, the insert and display opening 14 is herein shown as provided or formed by omitting the top wall or relatively large wall of this box body; but said display opening may as well be provided b omitting either side wall or end wall or t two opposite walls, or suitable wall portion or portions; and the particular shape of the box is arranged to suit the particular occassion; the resent form being merely shown for the sa e of illustration.

The box body is made of suitable material, as cardboard, tin, composition, etc., so as to furnish sufiicient rigidity and provide proper protection to the inclosed articles against crushing.

The covering means 16 used for closing the insert and display opening 14 preferably consists of transparent or semi-transparent means to enable the articles 15 to be visible and be displayed therethrough; and it is made flexible or in pliable sheet form, so that its edge portions or flaps can be properly folded over and sealed onto the adjoining wall portions of thebox body; and it is preferably also provided moisture-proof, so that the articles will be protected in the box against humidity and also will not readily adhere to said covering means.

In the practical use of this box I have found that cellulose papers, such as cellophane, in sheet form, are particularly adapted for use for this transparent or semi-transparent covering means, and either as a single sheet or in superposed layers or sheets.

The covering means is preferably in sheet form and is made sufficiently large in size to include edge portions or edge flaps which are adapted to project beyond the adjacent walls of the box body; and these projecting portions are provided with sealing means or adhesive means 17 which is applied thereto on one face of the sheet-like covering means only, and which can therefore be applied in one operation, for the. purpose of further economy. 1

In this method as illustrated in the drawing, in producing the complete and sealed box, the central portion of this sheet-like covering means, which is placed over the insert and display opening 14, is left devoid of adhesive means, and since it is of suitable material, like moisture-proof cellophane, it will not adhere to the articles 15 which are housed within the box, even though they are. sticky like some candies and the like are apt to be.

In sealing the box, after the articles 15 have been placed therein, the covering means 16 is laced over the insert or display opening 14, in the inverted position from that shown in Fig. 2; and by the first securing or sealing step of said means 16 onto the body 10 the edge portions or flaps of the former, which project beyond the side walls of the bod are bent down and secured onto said side walls by the use of the previously applied adhesive means 17 thereon, thereby forming side flaps 22 sealed over the side walls 12. This step also leaves end portions or end flaps 23 which extend horizontally beyond the end walls 13 of the body, and leaves corner portions 24-. which extend vertically beyond said ends, as all illustrated in Fig. 3.

In the following step in this method, the lower and outer parts of said corner portions 24 are pressed and secured with their adhesive means 17 onto said end walls 13, in such a manner as to form substantially diagonally or inwardly and downwardly extending folds or creases 25 therein, whereby each of said lower and outer parts of said corner ortions will assume substantially a triangu ar form or shape which is secured or sealed onto said end wall 13, as indicated in Fig. 4. This method of folding inwards and securing only such lower and outer part of the corner portion 24, in a substantially triangular form, onto saidend wall 13 as illustrated, leaves the larger or major part of the end flap 23 with its adhesive means free, so as to provide a large or broad intermediate lip which has its adhesive means ex posed and ready for use in the succeeding step.

In the next and final step, the large intermediate part or lip of said end flap 23 is pressed down and is by its adhesive means 17 secured onto the end wall 13 and over the underlying inner end portions of said triangular corner parts, as indicated in Fig. 5; thereby completely sealing the end flaps 23 onto the end walls 13, for protecting the inclosed articles, and without the necessity of any additional adhesive means being further applied to the exterior side of said covering means, adjacent said fold or crease 25, to secure the end flap onto its underlying corner portion and the end wall, as is usually required.

In Fig. 6 and Fig}. 7 I have shown a blank of material from w ich the box body is readily formed, thereby illustrating how my method is extended to include also the forming or shaping of the body along with the sealing or closing thereof by the application of my covering means 16. This blank of material has the corners suitably cut-away or omitted, and is preferably suitably creased as indicated by dotted lines 26, in Fig. 6, to form flaps which are readily bent up to provide the walls 12 and 13, as above set forth.

In this complete and entire phase of my novel method, the box body is arranged in its proper form or shape as well as being covered or sealed by a quick operation. This is accomplished by bending walls 12 and 13 up into the required position, and after placing articles 15 therein the covering means 16 is placed over the insert 0 ening 14 and sealed onto said walls, as set orth above, to

provide the complete box for displaying articles contained therein. The side and end flaps of the covering means extend substantially down to the lower edges of the walls 12 and 18 of the box body, whereby the cor ners of the box are closed also, and since said means is firmly secured to the walls at said corners by said adhesive means the walls are retained firmly in the proper position.

What I claim as my invention and desire to secure by Letters Patent is: v

1. A box comprising a body portion having a plurality of walls closed at one end and open at the other end, and substantially transparent cellulose sheet means mounted over said open end to retain and display articles positioned within the box, said sheet means having edge portions extending beyond the open top and providing sealing flaps, two opposite edge portions being secured onto two opposite walls of the body portion, corner portions extending from said edge portion and being secured to other walls of said body portion, in substantially triangular shape and leaving a relatively large lip between each pair of said triangular portions, and said lips being secured over the underlying parts of said corner portions and said walls to provide a complete seal'and produce a sealed box for protecting and displaying articles therein.

2. A box comprising a body portion having a bottom with side and end walls extending therefrom and the top being open between said side and end walls, and transparent cellulose sheet means mounted over said opening and having outer portions which provide sealing flaps extending beyond said walls, two opposite flaps being sealed over the side walls of the body portion, the corner portions of said sheet means, which extend beyond said flaps sealed on the side walls, being folded to form substantially triangular portions which are sealed onto said end walls, and the large intermediate remaining parts of the end flaps of said sheet means being sealed over the underlying parts of said triangular portions and said end walls, thereby roviding a sealed box for protecting and displaying articles contained therein.

'3. A display box consisting of two members, namely, a body member and a transparent covering member, said body member bein composed of relativel rigid material conslsting of a plurality 0 pairs of opposite walls which are closed at one end and are open at the other end, and said covering member consisting of cellulose sheet means mounted over said open end and having the outer portions arranged for sealing flaps to extend beyond said walls, two opposite edge portions of said sheet means bemg secured onto a pair of two opposite walls, corner portions extending from said seal-ed edge portions and being secured onto another pair of walls in substantially triangular shape and leavin a large lip between each pair of triangu ar portions, said lips being secured over the underlying parts of said corner portions and said walls to provide a complete seal over said open top.

4;. A display box consisting of two members, namely, a body member having an open top and a transparent covering member which closes said open top, said body member being composed of a blank of relatively rigid material having side walls and end walls bent up from its, bottom to contact at the edges and to provide a top display opening between said walls, and said covering member being composed of transparent cellulose sheet means mounted over said top display opening and having its outer portions providing sealing flaps which extend beyond said walls, two opposite flaps being sealed over the side walls of the body portion, the corner portions of said sheet means being folded to form substantially triangular portions which are sealed onto said end walls, and the large intermediate remaining parts of the end flaps of said sheet means being sealed over the underlying parts of said triangular portions and said end walls, thereby providing a sealed box for dis laying and protecting articles contained t iere- 1n.

In testimony whereof I have signed my name to this s ecification. H RMANN O. FISCHER.
